EOCENE FERNS.

DavallicB, but no known Fern resembles it so closely as Anemia adiantifolia} Sw., an 
inhabitant of Cuba, Bahamas, Florida, and Mexico to Bahia. 
Saporta has kindly compared specimens from Bournemouth with those of Sezanne, 
and writes respecting them, " Je n'hesite pas a declarer qu'il s'agit d'mie seide et meme 
espece." LesquereuX;, to whom we are much indebted, has also compared Bourne- 
mouth specimens with those from the Eocene of North America, and has written, "I do 
not see any difference whatever." 
Asplenium Fcersteri, Deb. and Ett., described in the ' Urweltliche Acrobryen des 
Kreidegebirges von Aachen,' pi. ii, figs. 4, 7, 11, is also closely related to, if not 
identical with, A. subcretacea. De Bey sees in them a close resemblance, but not 
identity. The specimens figured by Ileer in the ' Kreide-FI. der Arct.-Zone,' p. 93, 
pi. xxvi, fig. 1, as A. Fcersteri, seem to belong to quite a different species, and Dr. 
De Bey writes that this and other identifications were made without any comparison 
with his specimens. 
This Fern is found more especially to the east of Bournemouth Pier, and 
appears to have attained its greatest luxuriance when growing with Aroids and Conifers. 
It decreases in size and abundance in the beds westward, towards Poole Harbour, 
and at Branksea small pinnge only are met with, such as are drawn on PI. IX, figs. 
3 and 5. The specimen, pi. vi, fig. 6, ' Lignites of Bovey Tracey,' from Bovey, may 
belong to this species. Heer is confident that he has seen it from Alum Bay, but it may 
possibly have been erroneously labelled. 
A fragment of this Fern, probably the one just alluded to, was named Asplenium 
Martinsi by Heer, but not figured, and has been referred to in several subsequent 
works.
